Abstract

The new network paradigm of Software Defined Networking (SDN) has been widely adopted. Due to its inherent advantages, SDN has been widely used in various network fields such as data centers, WAN, enterprise, Optical Networks and energy Internet. Among them, SDN-based energy Internet systems are receiving more and more attention. But at the same time, some problems and challenges are gradually becoming more prominent. The SDN-based energy Internet is a distributed architecture for renewable energy, so the traditional centralized electric energy trading model will no longer apply. The blockchain has been rapidly developed and applied in various domains by virtue of its decentralization, coordinated autonomy, and non-tamperability. We propose an SDN-based energy Internet distributed energy trading scheme supported by blockchain technology. The proposed scheme achieves a reasonable match of the transaction objects under the premise of protecting privacy. Finally, we conducted a comprehensive, systematic security and applicability analysis of the proposed solution, further confirming that the system meets our design goals.

Highlights

Combining blockchain technology with Software defined network (SDN)-based energy Internet, we propose a distributed energy trading scheme based on SDN-based energy Internet background supported by blockchain technology
Our innovations are as follows: 1. We propose an SDN-based energy Internet trading scheme supported by blockchain technology

Summary

INTRODUCTION

With the continuous expansion of the network scale and the rapid growth of Internet traffic, the demand for traffic has been expanding, and various new services have emerged, increasing the cost of network operation and maintenance. X. Lu et al.: Blockchain-Based Distributed Energy Trading in Energy Internet: SDN Approach. With its unique technical advantages, blockchain technology perfectly solves the difficulties and challenges of energy trading in the above SDN-based energy Internet. We propose an SDN-based energy Internet trading scheme supported by blockchain technology. As the most promising technology, blockchain has been applied in many domains such as security and privacy [20], [21], Internet of Things, finance, public service, key management [22], searchable encryption [23] and so on. Dorri et al propose a new secure, private and lightweight architecture for IoT [28], based on blockchain technology, the approach is exemplified in a smart home setting [29]. Guan et al propose a secure and efficient energy trading scheme in IIoT-enabled energy internet based on blockchain [32].
